A transcutaneous access device includes a subcutaneous skirt, a transcutaneous neck and en extracutaneous telescoping sleeve all of which may be made of an inexpensive plastic material. Preferably, the skirt and neck are covered with a porous bed material which encourages the growth of tissue and collagen. The device functions as a conduit for a catheter and is sized to minimize contact with the catheter and to allow vertical and horizontal motion of the catheter relative to the implant portions of the access device so that torsion and stretching of the tissue adjacent to the implanted access device caused by normal body motions do not upset the biological seal that forms around the access device.

L'invention porte sur un dispositif d'accès transcutané comportant une jupe sous-cutanée, un col transcutané et un manchon télescopique extra-cutané pouvant tous être faits d'un matériau plastique bon marché. La jupe et le col sont de préférence recouverts d'un lit d'un matériau poreux favorisant la croissance des tissus et du collagène. Ce dispositif, qui sert de conduit pour l'introduction d'un cathéter, est dimensionné pour réduire les contacts avec le cathéter et permettre des mouvements verticaux et horizontaux du cathéter par rapport aux parties implantées du dispositif d'accès, de sorte que la torsion et l'étirement des tissus entourant le dispositif d'accès implanté, dus aux mouvement normaux du corps, ne compromettent pas l'étanchéité de la barrière biologique entourant le dispositif d'accès.
